This invention relates to the process known as carding in the manufacture of textile fabrics. g

It is substantially an improvement on patent issued to me, Eddo-V. 'Bateson method and apparatus for carding fibrous material, $11,534,564, April 21, 1925.

Garding machines for carding fiber especially of wool are-now usually arrangedin what are known as sets. A set may be a first breaker and then either a diagonal or scotch feed followed by a second breaker and finisher which may be coupled together or the first and second breaker may be coupled together,

;' than a diagonal or scotch feed and the finisher.

In some cases, a first and second breaker are coupled together, then adiagonal or scotch feed and then an intermediate and finisher coupled'together. V V I In still other cases, there may be three main cylinders connected together by various methods with no intermediate or scotch feed. 7 This invention has particular reference to what-are known as coupled up cards particularly where there are two main cylinders connected by an intermediate doffer or tummer such as shown in the above patent.

I find that by using a. tummer preferably" of large size with reference to the two main cylinders and connecting them, suchtummer being covered with flat wire instead of card clothing, I get better results.

By card clothing, I mean clothing with anelastic or yielding foundation and round wire teeth.

Under fiat wire teeth, I include convex wire toothed card clothing, garnettiwire with saw teeth, and burr cylinder wire with flat-topped teeth, both known to the trade as metallic tooth wire.

Such metallic tooth. wire will not bend nor give, and convexwireteeth will bend or give 45 very little, while the round teeth of card clothing will yield and are permanently bentout ofishape with little difficulty. 1

. Any fiatwire tooth'is rigid and, if rigidly held may separate or even break the stock but will not yield.

However, short stock, dirt and grease fall in between t'he teeth of card clothingand it is necessary to strip the card clothingicylinder quite frequently iHOldGI tomake it most effective while I find by using fiat teeth on certain rolls, they are automatically cleaned andkept clean whereby stripping'by hand is almost entirely done away with and the V stock 'is more evenly'treat'ed'with much fewer' bunches. v r I In applicationfiledAugust 14,1930, Ser.

N0. 475,230f0r combination card clothing and flatwire carding? machine pending: herewith, I-have claimed the use of flat wire tooth workers and strippers engaging card clothing main cylinders and in' thisapplication I claim to be .the'first to use afi'at' wire tunv mer or dofier betweentwo-main' cylinders both of card clothing and also the use of a' fiat wire dofferito clear the secondinain cy-linder.

By forward running,applie-dtomolls: and

cylinders, .I' refer to the. direction" in which the top moves from the feed end of't'hecard" towardthe delivery end, or from left toright in the drawing, and by backward running I refer to the opposite direction. By forward pitching,applied to teeth, Irefer'to the rake,"

from base to point whenat'thetop'of a roll, being toward the delivery end' ofthe card, and by backward pitch I refer to the opposite pitch. i 7

It is believed that the stock is acted: upon as indicated graphically by the linesused in the views altliough'this cannot positivelybe determined.

I believe I 'am also the first" to use various} new combinations of card clothing'rolls en gaging flat wire' covered rolls" for: workingthe stock and also forstripping and'keeping.

clear certain rolls which it is desirable should be kept clear of stock.

By keeping such rolls clean, better stock is produced and hand stripping is reduced to a minimum. 1

The drawing showing the various rolls and other parts is substantially diagrammatic. Arrows indicate the direction of rotation and thepitch and various types of teeth, such as card clothing, fiat wire and fancy are shown graphically.

Fig.1 is a diagrammatic side elevation of a coupled up set of cards which might be the first andsecond breaker with any well-known lap feed." ,7 V

Fig. 2 is a diagrammatic side elevation of a coupled up set of cards which might be a second breaker and finisher or an intermediate and finisher the set being fed by ,a

feed of the scotch or diagonal type and deliv ering to a tape condenser.

Fig. 3 is a diagrammatic side elevation of a coupled up set of cards, which would ordinarily be a first and second breaker, associated with a breast to which stock'is delivered by any of the well-known feed devices.

In the drawing, in Fig. 1, 1', 1 may be feed rolls .which deliver the stock to a lickerin 2 which in turn delivers to a tumbler 3 all these .rolls being covered with flat wire.

The stock is picked up by the first main cylinder 13 covered with card clothing and is carded by the fiat wire covered workers 14 and 15 associated with which arethe flat wire strippers 114 and 115. p r I 16 is a fancy of any well known-type preferably covered with fancy card clothing.

17 is a tummer' or intermediate dolfer shown as of the same size as first and second main cylinders 13 and 19. This tummer is covered with fiat wire and turns backward.

It is in stripping contact with main cylinder.

13 and in carding contact with second main cylinder 19. V

Preferably I use an angle doffer stripper 50 covered with fiat wire below and between 17 and19 whereby tummer 17 is thoroughly stripped of stock whichis delivered onto the second main cylinder 19.

On that account at the point 51 carding takes place and while some of the stock con tinues to cylinder 19, the lumps and parts which stand up on top of the teeth are carried back to another angle stripper 52 which is covered with fiat wire and turns backward. This again cleans tummer 17 and returns the stock to the first main cylinder 13 to be again reworked. V

stock leaving the teeth of cylinder 13 clean to pickup more stock from tumbler 3.

Second main cylinder 19 is covered with.

with fancy card clothing and is delivered to the doffer 123 which as shown is covered with flat wire. From this doffer, the stock is removed by a comb 24 of'the usual type.

In Fig. 2, the first and second main cylinders 13 and 19 together with their workers 14, 15, 20 and 21, strippers 114, 115, 120, and 121 and fancies 16 and 22 are the same as in Fig. 1 as is'a'lso the tummer or intermediate dotfer17; i

This view shows a second breaker and finisher, or intermediate and finisher coupled .together with a, feed A shown in diagram.

This feed may be of the diagonal or scotch typ i I: V 3 1 l In this feed, the stock 40 in the'form of a rovingis carriedb-etween moving rolls 41, 41 and deposited on a traveling apron 42 from which it is taken by feed rolls 44, 44 and delivered to a lickerin 43 and delivered to the first main cylinder-13. f

The second doffer 23, however, is covered with card clothing and the stock from it is removed by a comb 24 from whence it passes to a tape condenser T ofany well known type shown as having-the receiving rolls 30 and 31 around which the tapes pass.

In Fig. 2 is shown'an angle stripper 54 which strips tr mmer 17 after the stock has been carded between it and second main cylinder 19so that'the'flat wire teeth of 17 are alwavskept clean to receive stock from first main cylinder 13. I In Fig. 3, I show the feed as a flat wire breast such asshown in patent to Eddo V.

Bates ongarnett worker breast'for 'wool' cards #1568319, February 15, 1921 including feed rolls K and L, lickering, breast cylinder D, tumbler F, worker C and stripper B.

This breast delivers stock to the first main cylinder 63. As shown, all the rolls of the The first main cylinder 63 covered with flat wire teeth which pitch forward while the cylinder runs forward.

Associated wi h ma1n:cylinder 63 is thefiat wire covered worker 64 with fiat wire covered stripper 164.

Fancy 65 has fiat wire teeth which pitch 7 backwardand runs backward. Fancy stripper ,66has flat'wire teeth which pitch backward. It runs backward and takes most of the stock from fancy 65 and carries it up on the points of the teeth of cylinder 63. Fancy stripper 165 catches any stock which fiies' in the other views as is also the fancy 22 while the doffer 123 is covered with fiat wire and is cleared by a comb 24 as shown in Fig. 1.

The workers and 71 which work or card the stock on second main cylinder 19, instead of being covered with flat wire are covered with card clothing as are also their strippers 170 and 171.

In all cases, I prefer to use a tummer or intermediate dc-fler covered with flat wire the teeth of which pitch forward and which runs backward and which is in carding relation with the second main cylinder.

The teeth of the tuminer are preferably cleaned by one or two angle strippers before they reach the teeth of the first main cylinder.

The surface speeds of the various rolls expressed in feet per minute may be feed rolls 1, 1, 44;, 4 1-; K and L about 20; workers l i, 15, 20, 21, 64, 70 and 71 about 2%; strippers 114:, 115, 120, 121, 164:, 170 and 171 about 800; main cylinders 13, 19, and 63 about 1,000; tummer 17 from 60 to fancies 16, 22 about 1,200; doffer 23 from 50 to 60 and dofiers 123 from 60 to 100; angle strippers, 50, 52, 67 and 54 from 60 to 100; lickerin 2, about 200, tumbier 3 about 450; lickerin 43 about breast rolls, stripper B, 30, breast cylinder D, 150, breast worker O, 2 1, lickerin E. 150 and turnbler F, 450. Fancy 65, 8,000, fancy stripper 66, 1,200 and fancy stripper 165, 300.
